Finally a little more electrical completed. I found a 30amp Southwire transfer switch on sale for $48 and decided I had to have it. This automatically transfers the power supply from the inverter to the incoming shore power when plugged in. No messing with turning the inverter off, or manually switching anything.
The 1200W Giandel Pure Sine Wave inverter is enough to run the fridge, so good enough for now. With the transfer switch it powers everything plugged into the distribution center, with the exception of the A/C.
I needed to make sure the 12v converter in the distribution center only ran when plugged into shore power, and not the inverter. To do this I tied the 120v converter power line into the 120v incoming line before the transfer switch. That way the converter only runs when shore power is plugged in, and not off of the inverter. A separate 30amp breaker was added in the switch housing for this line, so it is still protected. As a bonus this freed up a breaker slot in my 8900 series WFCO distribution center so the bathroom will be on its own breaker.


Not sure if this is the final configuration. I have a Hughes 30amp Power Watch Dog that might get installed inside. I bought it for my previous camper and never used it. It's meant to be plugged in to the pole outside. However, because of laziness or convenience, it never got used.
